MOT Stats
UK Nationwide vehicle reliability data distilled from MOT tests.
Predictive model risk
Search any vehicle by registration, or pick a saved or recently searched car, to see its pooled fail rate, which component areas it fails on, and the typical mileage before those failures build up.
Failure rates by cohort
Share of tests failing by mileage band, vehicle age, fuel type and engine size.
Best & worst on the road
Models with the highest and lowest failure rates among cohorts with at least 500 pooled tests.
Most tested cars
The top 10 cars in the UK by pooled MOT test volume, ranked by sample size with failure rate and typical annual mileage.
Common failures
Ranked by number of recorded MOT failures. Bars show each area's share of the analysed failures.
